Beskrivelse
Summary:The groundnut Arachis hypogaea L. is an important crop in both commercial and subsistence agriculture in arid and semi-arid regions of the world. Fungal leaf spot disease has been a major destructive disease of peanuts and can cause yield losses of up to 50% or more. Pathogens include Pythium spp., Rhizoctonia solani, Sclerotinia minor Jagger, and Sclerotinia sclerotiorum (Lib) among others. These pathogens cause similar symptoms in the field; therefore, a proper diagnosis is needed so that proper management strategies can be implemented. The present study aims to carry out a bibliographic review on the main diseases of the peanut crop in Ecuador. The main diseases in peanut cultivation can be divided into diseases that attack seedlings in phenological stages V1 and V2, that attack stems and roots (including pods) and foliar diseases from R1 to R8. The implementation of management practices that increase the natural populations of potential bio-controlling agents can be a useful strategy in the control of diseases caused by soil fungi in peanuts. The genetic improvement of peanut species is of vital importance for the improvement of yields and must go hand in hand with the transfer of technologies for small producers.
